All you need is your prescription and your pupillary distance (PD). Outside of any special circumstances, your doctor will readily give this to you upon request if you can’t find it. It’s the law in all 50 states.
About Your Prescription
Your prescription provides us with your doctor’s recommendation for clear and comfortable vision. Please take a brief moment now to review your information with our 3 samples shown here. They represent 3 different ways of writing the same prescription:
Note, particularly:
- Â Your astigmatism correction (“cylinder”). Some doctors write their prescriptions in plus (+) cylinder and some in minus (-) cylinder. They are not the same. Take special note of this when entering your prescription later. If you don’t see anything there, leave it blank.
- “dist” (distance) is often abbreviated “D.V.”
- “near” (reading) is often abbreviated “N.V.
- For reading-only glasses: Some doctors will write the reading prescription separately, in its entirety (as “NEAR” or “N.V.” or “N.V.O.”), as in SAMPLE Rx #3. If this is the case, enter the power in the BOTTOM half of the form (you’ll see; it’s easy), and leave the ADD power blank (“0.00”).
- If you do not understand ANY part of your prescription, please call us to ensure everything is entered correctly. Don’t be shy; we are here to help, and we want your glasses to be made exactly to your doctor’s specifications.
